Norwegian Cruise Line Holdings announced it will restructure its board of directors following an agreement with activist investor Elliott Investment Management. The cruise operator said the board changes are part of efforts to address operational challenges that have affected the company's performance.

Separately, Carnival Corporation lowered its full-year profit outlook due to rising fuel costs driven by higher oil prices. The cruise line said strong customer demand and increased onboard spending are helping to partially offset the financial pressure from elevated fuel expenses.

In European markets, shares of Spanish energy company Enagas surged after the country's regulator announced new renewable energy incentives. The remuneration incentives could benefit Enagas as the company transitions its business focus from natural gas operations toward hydrogen energy projects.

The Norwegian Cruise Line board restructuring follows discussions with Elliott Investment Management, though specific details of the agreement were not disclosed. The activist investor had previously raised concerns about the cruise operator's operational performance.

Carnival's reduced profit guidance reflects broader industry challenges as energy costs impact transportation companies globally. Despite the headwinds from fuel expenses, the company noted continued strength in consumer booking patterns and passenger spending while aboard ships.
